Usage of spmd in matlab

Can the spmd parallel structure in MATLAB be used to simulate multiple independent computing nodes that can communicate with each other? That is to simulate each process as a computer.

Hi @yuxiao qi,

Yes, the "spmd" parallel structure in MATLAB can be used to simulate multiple independent computing nodes that can communicate with each other. To do so, you may treat each worker or separate MATLAB process as a simulated computing node, and these nodes can exchange data using "spmdSend" and "spmdReceive" functions.

Refer to the following section of "spmd" documentation for more information and an example:

Also, refer to following documentations for better understanding:

• https://www.mathworks.com/help/parallel-computing/spmdreceive.html

Hope this helps!
